Patent GB-800471-A (GB)
Abstract: 800,471. Control systems for ordnance operating against aerial targets. CONTRAVES AKT.-GES. Oct. 15, 1954 [Oct. 15, 1953], No. 29756/54. Class 92 An aerial target observation system comprises search apparatus located at a main station A, Figs. 1, 7, for finding the range a and azimuth angle # of a target Z with respect to the main station, aiming apparatus located at a station B remote from station A, a computed M associated with the aiming apparatus 4 into which are fed signals representing the distance d between the stations A, B, the range a and azimuth angle cc determined by the search apparatus and the angle of elevation # to which the aiming apparatus is adjusted: a control device adjusts the azimuth angle # of the aiming apparatus which control device is actuated by the computer M in such manner that the line of sight of the aiming apparatus is at all times a generatrix of the cone having the remote station B as apex and the vertical circle K centred on the main station A and passing through the target Z as base. The aiming apparatus is adapted to follow a located target and supplies the continually varying polar coordinates of the target to a check computer R which is also supplied with a signal representing the distance d and transmits to the main station signals representing the polar co-ordinates of the followed target with respect to the main station, so that a continuous check is given by the remote to the main station whether the correct target is being followed. From the information supplied to the computer M, the range b and azimuth angle # of target with respect to station B is derived and transmitted to station B to automatically position the azimuth angle of the aiming means there so that the range b is a generative of a cone having station B as apex and the vertical circle K as its base. Acordingly as the angle of elevation # is varied, the angle # is automatically varied so that the line of sight is constrained to move over the cone-shaped shell until the proper angle of elevation is reached and the target sighted. In operation, the commander at main station A chooses a target Z and the data a, #, d is transmitted to computer M associated with remote station B strategically located for firing at the target. The operator at B varies his viewing means from 0 to 90 degrees in elevation and this varying quantity # is transmitted to the computer which derives an azimuth angle # and range b corresponding to the range from the station B to the chosen target. The calculated value # is transmitted back to station B and automatically positions the azimuth angle of the viewing means, which must then intersect the target. When the target is sighted the proper angle # is determined and the calculated values from the computer are the correct values for the sighted target.
